1. An optical transmitter, comprising:

  • a rate adjustor configured to receive a reference clock and an input data and to output an output data synchronized with the reference clock;

    an electrical-to-optical converter configured to receive the output data from the rate adjustor, to convert the output data into a corresponding optical data and to output the optical data;

    a voltage-controlled oscillator configured to output the reference clock with a frequency controlled by a control signal; and

    a compensating unit including a temperature sensor to sense a temperature of the voltage-controlled oscillator, the compensating unit outputting the control signal based on the temperature sensed by the temperature sensor, wherein the frequency of the reference clock output from the voltage-controlled-oscillator is compensated for the temperature.
